In this section, we’re address some of the most FAQs regarding lawn mowers under $400.

Is a budget-friendly lawnmower worth it?

It certainly can be. If you have small yards, a riding lawnmower is definite overkill. Even homeowners with large yards can find value in inexpensive lawnmower models, provided they’re willing to spend a bit more time recharging the batteries or more money on filling the gas tank. If you’re a DIY landscaper, then low-cost lawnmowers can offer the best value for your dollar. 

What is the best lawnmower for a large garden?

The ideal lawnmower depends on the exact measurements of your lawn and how much time you can tolerate under the sun. What’s clear is that a self-propelled lawn mower eases the task of maintaining large gardens by doing most of the heavy lifting. With one of these bad boys, all the user has to do is follow along and turn the lawnmower from time to time. 

How many hours will a lawnmower motor last?

The lifespan of a lawnmower’s motor depends on the make and model. On average, residential-grade, budget-friendly models have a lifespan of between 400 and 500 hours. However, a brushless motor can last for upwards for 1,000 hours with regular upkeep. 

How much should I spend on a lawnmower?

Just like when purchasing jack stands, you should get the best model that you can afford. Whether you have a set budget of $400 or $4,000, the best lawnmower in any price category is worth the investment. Of course, we’re assuming you do your own landscaping and want the most reliable lawnmower model.


And that concludes our guide on the best lawn mowers for under $400.

We’ve spent tens of hours researching and trying out different models so you won’t have to.

Hopefully, our assessment of these six inexpensive lawn mowers will help you find the perfect model for your home.
